GLW buy-the-dip

Buy Corning (GLW). The fundamentals are still strong: Q2 core sales +17%, core EPS +30%, optical communications +32%, and major capacity expansion tied to Nvidia/Meta/Amazon. The selloff is driven by softer guidance and valuation, but the company is executing on the Springboard Plan (run-rate ramp to $30B by 2028). Technicals are washed out: below the 200-day and key support, setting up a mean-reversion bounce toward the prior breakdown zone.

Key Risk: Guidance keeps deteriorating for multiple quarters, proving the “soft guidance” was not a one-off and demand/capacity ramp is slipping.

GLW valuation short-term hedge

Sell short Corning (GLW) for a continuation move to ~$100. The stock broke below the 200-day and key support levels and is flagged as extreme oversold; when valuation is stretched (forward P/E ~45 vs sector ~24), markets often demand further de-rating before buyers step in. This trade targets momentum/positioning pain after the -12% premarket shock.

Key Risk: A rapid re-rating catalyst hits (strong follow-up commentary, major customer pull-ins, or guidance upgrade) that triggers a sharp squeeze before $100.

  • Corning stock dropped by over 12% in the premarket session.
  • The company published strong earnings but issued soft guidance.
  • There are concerns about the company’s valuation.

Corning stock plunged by over 12% in the premarket session after the company published the latest earnings report. GLW dropped by 12% to $122.92, its lowest level since March 9 this year. It has plunged by 54% from the year-to-date high of $271, with its valuation falling from $219 billion to $123 billion. 

Corning stock drops after its earnings report

Corning, a top company that manufactures the popular Gorilla Glass, display glass, and advanced optics solutions, has been in a strong bull run this year, helped by its partnerships with companies like Nvidia, Meta Platforms, and Amazon

These deals will see the company boost its optical connectivity manufacturing capacity by about 10%. It will also expand its fiber capacity by over 50%, including three manufacturing plants in the country. 

As a result, it aims that these deals will help it meet its Springboard Plan, which aims to grow its annualized run rate of $20 billion by the end of this year to $30 billion by the end of 2028. It aims to grow this figure to $40 billion by 2030.

Still, despite these metrics, the stock has dropped sharply after releasing its results. Its results showed that its core sales jumped by 17% in the second quarter to $4.74 billion, with its core EPS rising by 30% to 78 cents. Its optical communications sales jumped by 32% to $2.07 billion. 

By segment, its optical communications revenue jumped by 32% to $2.07 billion, while the glass innovations segment rose by just 1%. The automotive segment rose by just 2%, while its solar business soared by 90% to $438 million after completing a prolonged maintenance shutdown. In a statement, Wendell Weeks, the CEO, said:

“We continue to deepen our long-term customer partnerships with industry leaders, most recently with Amazon and NVIDIA. These partnerships provide strong proof points supporting our exciting Springboard Plan.”

Softer guidance and valuation concerns

A key concern among investors is that its guidance was relatively softer than expected. It now expects that its third-quarter sales will rise by 16% to between $4.9 billion and $5 billion.

At the same time, there are concerns that the company’s business has become highly overvalued. The company has a forward price-to-earnings ratio of 45, higher than the sector median of 24. 

Despite this, analysts believe that Corning has more upside to go. Citigroup’s Asiya Merchant boosted his target from $225 to $240, while Oppenheimer boosted from $210 to $230. Bank of America’s Wamsi Mohan sees the stock soaring from $223 to $243.
